3.5GHz Downconverter Mixers
with Selectable LO Doubler
12
______________________________________________________________________________________
Detailed Description
The MAX2683/MAX2684 are double-balanced down-
converter mixers optimized for the 3.4GHz to 3.8GHz
frequency band. The MAX2683 is designed for down-
conversion to IF frequencies of 100MHz to 400MHz,
while the MAX2684 is designed for IF frequencies of
800MHz to 1000MHz. In addition, the devices include a
logic-level LO frequency doubler, an integrated LO fil-
ter, and externally programmable bias control circuitry.
RF Input
RFIN is a single-ended input that accepts frequencies
in the 3.4GHz to 3.8GHz range. It requires a matching
network and a DC-blocking capacitor that may be part
of this network. See
Typical Operation Circuit
for rec-
ommended component values. See Table 1 for RFIN
port S-parameters.
LO Inputs, LO Frequency Doubler,
and LO Filter
The MAX2683/MAX2684 feature an internal LO frequen-
cy doubler that allows the external LO to run at full or
half frequency. Running the LO at half frequency has
the benefit of reducing unwanted LO leakage through
the low-noise amplifier (LNA) to the antenna, reducing
injection pulling of the voltage-controlled oscillator
